The influence of noncoordinating anions is analysed in an extension of our systematic investigations into iron(II) spin-crossover coordination polymers. We present here ditetrazole complexes of iron(II) tetrafluoroborate where the two tetrazole moieties are separated by alkylene spacers. The number of carbon atoms in the spacer (n) was varied between n = 5-10, 12, and the complexes were compared with their ClO4- analogues...
